If your desk isn't cluttered, you can have your very own red Dalek (from the Smarties genome of Daleks - first scene in "Victory to the Daleks") patrol on top of it. Simply turn on the 8 cm Dalek and place it on your desktop (or other flat surface). His sensors will prevent him from falling off your desk and bumping into your DVD collection and credit card bills. At every turn, the Dalek has a need to "EXTERMINATE" but you can turn this feature off if it gets too annoying.
